unfortunately I cannot figure out how to run it on the device
I tried several stuff, including creating a .desktop file hoping to got an icon and be able to start the app from the phone's touch interface. Maybe I'm just configuring the .desktop file the wrong way. Is there some link you can suggest to understand how to write it properly and where to place it?

From an ssh shell I tried running directly the binary or the qml file (with qmlscene)
Apparently I do not got an error, but I cannot see anything on the phone screen.

I read online that the app is started "minimized" by default and I can maximize it form the App Lens, but I cannot see it there either.
